This paper analyzes the information asymmetry between owner/manager and lenders. More specifically, the research investigates the role of corporate governance mechanisms in reducing the agency costs of debt. The findings show that lenders perceive higher agency costs of debt if the controlling shareholder owns a percentage of capital greater than 66%. Results also show that the presence of independent directors elected by minority shareholders on the board mitigates the agency conflicts between borrowers and lenders. In the same way, the audit committee independence reduces the agency costs of debt. Moreover, the study shows that when the audit committee chairman coincides with the board chairman banks perceive more risk and, therefore, a bigger asymmetry. This coincidence increases the concentration of power in the hands of just one person and this enhances the likelihood of opportunistic actions by the management that could damage lenders. This means that it is costly for companies to concede to just one person too much influence over the board activities, because it reduces the effectiveness of the monitoring role played by independent directors, increasing the information asymmetry between borrowers and lenders.
